VALVE.

Specification of Letters Patent.

Patented Nov. 22, 1910.

To alt whom t may concern:

Beit known that I, GUIDO ySoHUs'rnn, a subject of the King of Hungary, and a resident of Besztereze, Austria-Hungary, have invented a new and improved Valve, of which the following is afull, clear, and exact description. i

The invention is an impro vement in valves for pneumatic vehicle tires, cushions and other air-inflated articles, and has for its purpose to prevent possible leaking of the air through the valve after the article has been inflated.

To this end .I construct the barrel or tubular body through which air is introduced into the article, of an inner and outer section, the outer section threaded into the inner section and having upper and lower external shoulders, a cap threaded on the outer end of the outer section of the tubular body, and a packing seating on each shoulder, with the lower packing forming an air-tight oint between the sections of the tubular body,

and the'upper packing forming a `fluid-tight joint between the outer section of the tubular body and the cap.

eteience is to be had to the accompanying drawingsl :forminor a part ot this specification, in which simi ar characters of reference indicate corresponding parts in both views.

Figure 1 is a central longitudinal section through a valve embodying my invention as applied to the tire of a motor cycle; and Fig. 2 is a cross-section of the same on the line 2 2 of Fig. 1.

The valve embodies in its construction an externally-threaded barrel or tubular body 5, having an inner removable section 6 threaded therein, and provided with a mushroom head 7, between which and a nut 8 threaded on the body, is adapted to' be clamped the inner tube' 9 of a tire or other air-inflated article, a strong air-tight conneetion at this point being lnsured by placing a metal Washer 10 directly under the nut, and a rubber washer 11 between the washer 10 and the inner tube. To the upper or outer face of the nut 8 are clamped the overlapping edges of the outer rubber tube 12, by a nut 13 threaded on the tubular body and binding on the rim 14.

The outer removable section 6 of the valve body is externally threaded at its outer end to receive a cap 15, and at or near the center is provided with enlargements or collars 16,

the faces ottl which, respectively adjacent to the cap and'inner section 5 of the tubular body, are grooved to receive gasket-s 17 of rubberl or other suitable material. By this arrangement an air-tight joint is afforded between the two sections ot' the valve body when the outer section is tightened, and a like joint is provided between the cap and outer sectionvof the tubular body when the cap is tightly threaded to place. 15 is provided with a cylinder 18 of sulficient diameter and length to envelop the joints afforded by the gaskets when the cap is assembled, the inner Aend of the cylinder bearing on a lock nut 1S) threaded on the. inner section ot' the valve body and preventing the cap from working loose.

The inner end of the outer section y6 ofthe valve body is conically bored to form a seat for a valve 20, the valve having an outer jacket 21 ot' rubber or other equivalent material to insure the absolute cutting off of the air from the inner tube when the valve is seated, the jacket being securely united with the valve by providing the latter with a number of circumferentlal grooves into which the rubber projects. The stem 22 of the valve passes outwardly through the outer section 6 of the valve body a substantial distance, where it is threadedinto the tubular.

shank or stem 23 .of a valve 24, the latter seating on the outer end of the tube 6 and having a cross slot 25 in its head for the insertion of a screw-'driver in drawing the two valves together or removing the outer valve from the tube. The inner section of the tubular body 5 is counterbored for the greater portion of its length and receives a bushing 26, the bore of which forms a guide for an extension piece 27 rigid with the valve 20, the said piece being flattened at each side, as best shown in Fig. 2, in order that it may not substantially interfere with the passage of the air into the inner tube when the latter is being inflated. A head or collar 28 is formed on the extension piece 27 and is adapted to seat on the outer end of the bushing 26 and limit the inner movement of the valve 20. A

In infatin the tire or other article to which the va ve lis a plied, the cap is first removed, after which) the valve 24. is unscrewed and withdrawn. A. pump bose is then applied to the outer threaded end of the tube 26, as is the usual practice, and the inflation of the tire proceeded with. The

The cap i joint at both, points. A further airetight is applied, thus joint is effected when the cap 1fl'erent places.

sealing the valve at three Having thus describedmy invention, I claim as new and desire to secure by Letters Patent:

1. In a valve for air-inflated articles, a tubular body through which the air is introduced into the article, constructed of two sections, the louter section threaded into the inner section` and having an intermediate portion provided with annular grooves on the inner and outer faces thereof, each groove having a packing, with the packing of the inner groove forming an air-tight joint between the two sections of the body, and a cap threaded on the outer end of the outer section of the body and forming an air-tight joint with the outer packing.

2.' n a nozzle for air-inflated articles, a tubular body through which the air is' introduced in inflating the article having an outer removable section threaded therein, with the outer section provided with an intermediate enlargement having an' annular groove in the outer and inner faces thereof, packings within said grooves, with the pack- 1n of the inner groove forming an air-tight joint between the two sections of the body,

and a cap threaded on the outer end of the tubular section of the body and forming an air-tight joint with'the outer packing andl having a cylinder projecting therefrom, inclosing the said enlargement.

3. In a nozzle for air-inflated articles, a tubular body through which the air is introduced in inflating the article, having an outer removable section threaded therein,

with the vouter section provided with an inte'rmediate enlargement having an annular groove in the outer and inner faces thereof,

packings within said grooves, with the pack- 1n of the inner groove forming an air-tight joint between the two sections of the body,

a cap threadedon the outer end of the tubu- -outer section, the outer section having troduced into the article, constructed of an inner and an outer section, the outer section \threaded into the inner section and having up er and lower external shoulders, a cap threaded on the outer end of the outer sectioriof the tubular body, and a packing seating oneach shoulder, with the lower packing formingean-air-ti ht joint between the seetions of the tublar body, and the upper packing forming a fluid-tight -joint between the outer section of the tubular'body and the cap. c

' 5. In a valvefor air-inflated articles, a tubular body through which the air is'introduced into the article, constructed of an inner and an outer section threaded together, and a cap threaded on the outer end of the externally-arran ed packin respectively formin a iiui -tight joint etween the sectionso the body and the outer section of the body and the cap. c

6. In' a valve for air-inflated articles, a tubular body through which the ail-is introduced into the article, constructed offan inner and an outer section threaded together,
